Application filed July 18, 1917. Serial No. 181,260.

To all whom it may comer n:

Be it known that I, THOMAS W. L. Mc- GUIRE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented ollowing is a chamber *by the engine, thus as the speed of the engine increases or diminishes the j supply of volatilized fuel is proportionally increased or diminished. 30 In carrying out the invention,

a number of perforated disks in ing chamber of the carburetor. are fixedly-mounted upon a shaft driven by a fan, which in turn is controlled by the suc- I employ the mix- 'tion of the en 'ne. As the disks revolve they carry up ydrocarbon oils into an air space in the mixing chamber, where they are subjected to a stream of air assin through said mixin chamber, to t e en state into the en e.

While the car ureter may be used to advantage on difi'erent types of-explosive engines, it is particularly eflicient when, used m connection with the multicylinders of an automobile engine and is adapted to supply the same with volatilized fuel, irrespective of the an le it may assume in ing u or down hill, or whether its inta e mani old be arranged at a higher or lower level than the carburetor.

Other objects will hereinafter a pear as the inventionis described in conn on with the accompanying drawin in which:

In carrying out the invention, I employ a container 1 which may be located at the rear of the automobile in lieu of the gase line tankusua'lly employed. Said container 1 has a centrall disposed mixing chamber 2 divided into t ree compartments 3, 4 and 5, by partitions 6 and 7, which extend only part. way to the top of the chamber 2 to leave passageways '9 and 10 for the flow of air and fuel mixtures, as will hereinafter appear.

An airintake 14 communicates with the upper portion of the mixing chamber 2, w ich has outlet ports 15 and 16 at its opposite ends communicating with an outlet duct 18, which communicates at one end with a port 20 leading into a chamber 22, containing a suction fan 23. Access is bad to the duct 18 and the ports 15, 16 and 20, through a removable cover 24 secured to the upper portion of the mixing cham- The suction fan 23 is fixedly-mounted upon a centrally-disposed shaft 25, extending longitudinally through the mixing chamber 2 and 'ournaled in a bearing 27, fixed to one end of said mixing chamber 2, and in bearin s 29 and 30 carried by the partitions 6 and l, respectively. Said shaft 25 is also journaled in a stufiing box 32, secured to'an end wall of the compartment 5 to prevent the fluid therein from flowing into the fan chamber 22. One end of the shaft 25 projects through the outer wall of the fan chamber 22 (Fig. 4), and terminates in a rectangular portion 35, to receive a crank (not shown) whereby it may be initially rotated to obtain a supply of volatilized fuel to start the engine.

Within compartments 3, 4 and 5 of the mixing chamber 2 are perforated disks 37 and 38, which, as they revolve, carry the fluid or fluids in said compartments u into the air s ace above-the level of such uids where- 10! ey are volatilized by the incoming air which enters the intake 14 and escape through'the outlet ports 15 and 16. The disks ,38 embody wire or other suitable fabric which takes up more of the fuel than the smooth sides of the disks 37.

The mixing chamber 2 receives fluid from oppositely-disposed supply chambers 40 and 41 closed at the top with covers 40 and 41, res ectively. Chamber 40 is divided into t ree com artments by partitions 42 and 43, and c amber 41 is divided into three compartments by partitions 44 and 45. The compartments of chamber 40 communicate with the compartments 3, 4 and 5 of the mixing chamber 2 through ports 46, and the compartments of chamber 41 communicate with said mixing chamber compartments through ports 47. In practice the number of compartments may be increased or diminished as preferred. Fluid is introduced in the compartments of cham ber 41 through inlets 48 normally closed by 'caps 49, to exclude dust and other foreign matter. Drain cocks 50 leading from the bottom of the chamber 41 are provided for draining ofl' the fluid and any accumulation of sediment.

51 designates a fuel mixture storage receptacle arranged above the chamber 40.

for reserving a supply of fuel mixture from the mixing chamber 2. Fuel mixture is introduced into said storage receptacle..51

through a' branch duct 52, communicating with a main duct 54, leading from the fan chamber 22 to the intake manifold A, of the engine B, to which it is connected by a check valve 55, which prevents the fuel mixture from flowing backward from the manifold into said main duct 54.

. A manually-controlled valve 57 is coupled to the main duct 54 to shut off the flow of fuel mixture therethrough to the manifold A, when it is desired to stop the engine. A deflector 60 extends into the main duct 54 where it communicates with the branch duct 52, for the purpose of deflecting a portion of the fuel mixture upwardly into the receptacle 51 through said branch duct 52. A check valve 63 is provided where the branch duct 52 enters the receptacle 51, to prevent the fuel mixture therein from flowing backwardly into said duct. An outlet duct 65 leads from the receptacle 51 to a manifold 66, for introducing fuel mixture directly into the combustion chambers of the cylinders of the motor when cranked for the urpose of starting the same. Said outlet not 65 has a valve 68, for controlling the flow of fuel mixture therethrough.

In practice, the container 1 is supplied with fluid to a level below the top of the partitions 6 and 7, so that it will not splash from one compartment to another in the mixing chamber 2. The partitions 42 and 43 in the chamber 40, and the partitions 44 kerosene and water can be used both efiiciently and economically in the production of a carbureted mixture for driving the engine. However, I do not restrict myself to the use of any particular kind or number of fluids. After the several compartments have been supplied with fluid, the carbureted mixture is initially produced by manually cranking the shaft 25, which operation rotates the disks 37 and 38, causing them to carry the fluid in the mixin chamber 2 upwardly into the air space t erein, where it is formed into said carbureted mixture by a current of air drawn into the intake 14 by the suction fan 23. As the carbureted mixture is formed it is drawn into the combustion chambers of the motor B, and exploded in the usual way to start and drive said motor B. Before the motor is cranked the valve 68 is closed, so that a portion of the carbureted mixturemay flow through the duct 52 and accumulate in the receptacle 51. When the engine is running the suction created thereby rotates the fan 23, which in turn drives the shaft 25 with the disks 37 and 38.

From the foregoing descri tion it is apparent that I have produce a carburetor embodying the advantages above enumerated, and while I have shown and described the preferred form of said carburetor, I reserve-the right to make such changes in the construction, combination, and arran ement of parts as properly fall within t e spirit and scope of the appended claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

In a carburetor, a liquid fuel mixing chamber having an air s ace, rota elements mounted in said mixing cham r to carry a portion of the fuel upwardly into ture.
